Journal ArticleDOI
Experimental long-lived entanglement of two macroscopic objects
TL;DR: The robust and long-lived entanglement of material objects demonstrated here to be useful in quantum information processing, including teleportation of quantum states of matter and quantum memory is expected.
Journal ArticleDOI
Experimental demonstration of quantum memory for light
Brian Julsgaard,Jacob F. Sherson,J. Ignacio Cirac,Jaromír Fiurášek,Jaromír Fiurášek,Eugene S. Polzik +5 more
TL;DR: Here a protocol for a high-fidelity transfer of an independently prepared quantum state of light onto an atomic quantum state based on atomic ensembles is proposed and experimentally demonstrated.
Journal ArticleDOI
Quantum teleportation between light and matter
Jacob F. Sherson,H. Krauter,Rasmus K. Olsson,Brian Julsgaard,Klemens Hammerer,Ignacio Cirac,Eugene S. Polzik +6 more
TL;DR: The teleportation of a quantum state between two single material particles (trapped ions) has now also been achieved and is demonstrated between objects of a different nature—light and matter, which respectively represent ‘flying’ and ‘stationary’ media.
Journal ArticleDOI
Experimental Realization of Highly Efficient Broadband Coupling of Single Quantum Dots to a Photonic Crystal Waveguide
Toke Lund-Hansen,Søren Stobbe,Brian Julsgaard,Henri Thyrrestrup,T. Sünner,Martin Kamp,Alfred Forchel,Peter Lodahl +7 more
TL;DR: Time-resolved spontaneous emission measurements of single quantum dots embedded in photonic crystal waveguides are presented, and an unprecedented large bandwidth of 20 nm is demonstrated, showing the promising potential of photonic crystals waveguide for efficient single-photon sources.
Journal ArticleDOI
Reaching the quantum limit of sensitivity in electron spin resonance
Audrey Bienfait,Jarryd J. Pla,Yuimaru Kubo,Michael Stern,Michael Stern,Xin Zhou,Cheuk Chi Lo,C. D. Weis,Thomas Schenkel,Mike L. W. Thewalt,Denis Vion,Daniel Esteve,Brian Julsgaard,Klaus Mølmer,John J. L. Morton,Patrice Bertet +15 more
TL;DR: This work improves the state-of-the-art sensitivity of inductive ESR detection by nearly four orders of magnitude, and demonstrates the detection of 1,700 bismuth donor spins in silicon within a single Hahn echo with unit signal-to-noise ratio.
